############################################################################### # Bug#17942050:KILL OF TRUNCATE TABLE WILL LEAD TO BINARY LOG WRITTEN WHILE # ROWS REMAINS # # Problem: # ======== # When truncate table fails while using transactional based engines even # though the operation errors out we still continue and log it to binlog. # Because of this master has data but the truncate will be written to binary # log which will cause inconsistency. # # Test: # ===== # Make master to wait in "open_table" call during the execution of truncate # table command and kill the truncate table from other connection. This causes # open table to return an error saying truncate failed during open table. This # statement should not be binlogged. ############################################################################### --source include/have_innodb.inc --source include/have_debug_sync.inc --source include/have_binlog_format_statement.inc RESET MASTER; --connection default CREATE TABLE t1(id INT AUTO_INCREMENT PRIMARY KEY, a INT, b INT) ENGINE=INNODB; INSERT INTO t1(a, b) VALUES(1,2),(2,4),(3,6),(4,8),(5,10); SET DEBUG_SYNC = "open_and_process_table signal truncate_before_lock wait_for forever"; --send TRUNCATE t1 connect(con1,localhost,root,,); SET DEBUG_SYNC = "now wait_for truncate_before_lock"; # Wait for one connection to reach open_and_process_table. --let $show_statement= SHOW PROCESSLIST --let $field= State --let $condition= 'debug sync point: open_and_process_table'; --source include/wait_show_condition.inc SELECT ((@id := id) - id) FROM information_schema.processlist WHERE processlist.info LIKE '%TRUNCATE t1%' AND state LIKE '%open_and_process_table%'; # Test killing from mysql server KILL QUERY @id; connection default; --ERROR ER_QUERY_INTERRUPTED --reap connection con1; --source include/show_binlog_events.inc disconnect con1; --source include/wait_until_disconnected.inc connection default; SELECT * FROM t1; DROP TABLE t1; SET DEBUG_SYNC= 'RESET';
